Dangerous

However, it would be extremely dangerous from this one calculation to assume that heuristic 4 is the most important, as the next example shows. 

In preliminary process design it mig] it be necessary to use marginal costs for steam, but the designer should keep in mind the dangers of using such costs. 

CH2=CHC = CCH = CH2. a colourless liquid which turns yellow on exposure to the air it has a distinct garlic-like odour b.p. 83-5°C. Manufactured by the controlled, low-temperature polymerization of acetylene in the presence of an aqueous solution of copper(I) and ammonium chlorides. It is very dangerous to handle, as it absorbs oxygen from the air to give an explosive peroxide. When heated in an inert atmosphere, it polymerizes to form first a drying oil and finally a hard, brittle insoluble resin. Reacts with chlorine to give a mixture of chlorinated products used as drying oils and plastics. 

X-rays find wide applications in X-ray photography and in crystallography. Prolonged exposure of the human body to the rays induces a dangerous form of dermatitis, and even sterility, but controlled exposures are applied to alleviate cancer.

Bettelheim draws on his experience in concentration camps to illuminate the dangers inherent in all mass societies in this profound and moving masterpiece. 

Another danger, intoxication by inhalation, is related to the benzene content. A maximum limit is often set for this compound. 

During drilling operations sometimes large volumes of drilling mud are lost into a formation. In this case normal mud circulation is no longer possible and the fluid level inside the borehole will drop, creating a potentially dangerous situation as described below. The formations in which lost circulation can be a problem are ... 

It was also shown, that serious defects were detected, which under normal circumstances could lead to dangerous situations in the following service periods and cannot be detected by the normal conventional testing method. 

Eddy Currents ttike their name from the swirls (eddies) observed in turbulent water flow. The Greek mythology tells us about Charybdis. A monster eddy current between Italy and Sicily whose attractive field pulled unwary sailors to their destruction. Our kind of eddy currents are usually not so dangerous, they flow in electrical conductors and are a branch of Electromagnetics. Where does that spring from Could it make eddy currents the very oldest NDT technique ... 

The main danger when using so much software is to never know if the version used is up to date. This problem was solved by identifying each software and hardware component of the instrument. 

The device is especially effective while inspecting ecologically dangerous installations, productions and facilities, choosing and determining repair-restoration technologies and operations. 

There are difficulties of detecting defects in axial canal because of solid sediment layer of 1. 2 mm thick on the canal surface. When using known defectoscope devices a preliminary labor-intensive mechanical treatment of the axial canal surface is needed. The experience of application of different methods of rotor axial canal control in multifunction automatic device ROTOR - K has pointed to the fact that the most effective method is eddy current one [1]. All the dangerous cracks were just detected by the eddy current method, the part of the cracks were not... 

The application of liquid couplants is not only inconvenient, but the results obtained tend to be sensitive to contact pressure, and there is always a danger of losing coupling. 

On Russia territory there are about 100 thousands of dangerous enterprises and objects, comprising about 1500 nuclear facilities and 3000 chemical and biological extremely hazardous objects. The average period of emergency situations is 10 — 15 years for accidents and disasters with the material loss up to 2 billion USDs, and 15 — 45 days, when the material loss is up to 100 million USDs. 

NDT devices used for the control of quality of critical products potentially dangerous for people and environment are subject to mandatory checking. 

Regardless of the amount of NDE applied no ship will last forever. Only when the costs of maintaining a vessel to the condition required by Class become unacceptable will a ship be scrapped. Through the more rigorous applicaton of NDE and the stringent imposition of repair procedures it is possible that the dangers posed by an aging fleet can be reduced. 

The miderstanding of molecular motions is necessarily based on quaiitum mechanics, the theory of microscopic physical behaviour worked out in the first quarter of the 20th century. This is because molecules are microscopic systems in which it is impossible—or at least very dangerous —to ignore the dual wave-particle nature of matter first recognized in quaiitum theory by Einstein (in the case of classical waves) and de Broglie (in the case of classical particles). 

We are aware of tire dangers inherent in predicting tire future. It is much safer to summarize tlie present and to extrapolate to tlie near tenn only. 

All the azides are potentially dangerous, and liable to detonate on heating, but those of the alkali and alkaline earth metals can be heated with caution if pure they then evolve pure nitrogen. 

With the danger of severe oversimplification, which unavoidably leads to improper underevaluation of important recent developments, I shall try to indicate where traditional, classical MD has brought us today, or will bring us tomorrow. This concerns the techniques rather than the applications, which cannot be reviewed in the present context. The main aspects to consider concern algorithms and force fields.

Hence, the main danger in the process of compiling test sets remains. Fortunately, there are some other approaches which, although they may look more sophisticated, do diminish the possibiHty of such incompatibilities.
